Specification of Letters Patent.

Patented Tan. 23, 1906.

Application filed September 9, 1905. Serial No. 277,665.

To all whom, it may concern.-

Be it known that I, PHILIP A. MYERS, a citizen of the United States,residingat Ashland, in the county of Ashland and State of Ohio,haveinvented certain new and useful Improvements in Hay-Carriers, ofwhich the following is a specification, reference .being had therein tothe accompanying drawings.

This invention relates to hay-carriers, and more particularly to thattype of carriers known as sling-carriers, intended primarily for use inconnection with a sling for-sup porting the load or bundle, althoughcapable of use in other connections.

The presentinvention is in some respects in the nature of an improvementupon the construction set forth' in my prior Letters Patent, Nos.786,455 and 786,456, of April4, 1905, and No. 795,001. of July 18, 1905,one of the objects of the invention being to do away with the aliningguide or pulley employed in the construction set forth in said LettersPatent for the purpose of holding the gripping-jaws ,in properalinement, so as to maintain the load in correct longitudinal position.

The invention has for a further object the "provision of a carrier whichmay be reversed either by drawing the rope through the carrier in onedirection or the other or by causing the body of the carrier to swivelrelatively to the carriage, such carrier having gripping devices whichpositively grip the rope by reason of the weight of the load, the bightof the rope hanging transversely with respect to the track, so that theload is carried in a position which is longitudinal or parallel to thetrack.

To these ends my invention consists in certain novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of astructure embodying my invention in one form. Fig. 2 is an end elevationof the same. Fig. 3 is a plan section taken on the line :1? m of Fig. 1and looking in the direction of the arrows. Fig. 4 is an inverted planview showing the under side of the annular flange or track whichconstitutes the carriage member of the swiveling connection between thecarriage and carrier-frame. Fig. 5 is an end view, partly in elevationand partly in section, illustrating the swiveling connection between thecarriage and carrierframe and the locking devices; and Fig. 6 is a planview of the movable part or member of the carrier-frame and the partsmounted or supported thereon detached from the-rest of the apparatus.

In the said drawings, 1 indicates a suitable track, and 2 a knockerthereon, the same being preferably constructed as set forth in my priorLetters Patent, Nos. 786,455 and 786,456. On this track travels acarriage 3, having wheels 4 to fit the track 1. The carrier proper orcarrier-frame is connected to this carriage by means of a swivelingconnection, so as to permit the carrier-frame to turn around a verticalaxis relatively to the carriage when it is desired to efiect thereversal of the carrier in this way. To this end the carriage isprovided with an annular flange 5, while the carrier-frame is providedwith a grooved annular flange 6 to receive the annular flange or track5. Preferably the carriage and carrier-frame are made in two partsdivided vertically, so as to permit the ready assembling thereof, as isusual in structures of this character.

As in my prior Letters Patent hereinbefore referred to, thecarrier-frame is made in two parts, one of which is fixed againstvertical movement relatively to the carriage, and is therefore termedthe fixed part or member, while the other is free to move verticallyrelatively to the carriage and said fixed part or member and istherefore termed the movable part or member. The former is designated asa whole by the referencemumeral 7 and the latter by thereference-numeral 8, the same being shown detached in Fig. 6 of thedrawings. The member 6 of the swiveling connection is formed on thefixed mtznlaer 7 of the frame, and said fixed member 7 is'provided witha spring-actuated locking-bolt 9, which is mountedto slide vertically in2. casing 10, carried by the fixed member 7.

11 indicates a spring which forces the bolt 9 normally upward, and 12indicates an eye formed on the projecting lower end of the bolt, towhich eye is attached a cord or rope 13, by which the bolt may beoperated. The swiveling member or track 5 of the carriage is provided atdiametrically opposite points with notches or recesses 14, adapted toreceive the end of the bolt'9. On one side of each notch or recess 14there is formed an abrupt vertical shoulder or stop 15, located in thepath of the bolt and preventing any rota,-

BEST AVAlLABLE COP tion of the carrier in one direction when the bolt isin operative position. On the other side of each of the notches orrecesses 14 there is formed an incline 16, so arranged, as indi cated inFig. 5, that it will ride over and press down the bolt when the carrieris turned in the opposite direction, providing sufficient force beapplied to the carrier to effect this result. The bolt, however, when inengagement with either one of the notches or recesses 14 will hold thecarrier in fixed relation to the carriage against all ordinary strainswhich tend to rotate the carrier-frame and will absolutely preventrotation of the carrierframe in the direction in which the path of thehoisting and hauling rope tends to move it by reason of the offsetrelation of the gripping-jaws to the central longitudinal plane of thecarrier, as hereinafter set forth.

The fixed member of the carrier-frame is provided with the stationarygripping-jaws, which are in duplicate and which are arranged at oppositeends and on opposite sides of the machine. They are indicated by therefer ence-numeral 17 and are shown as separate parts secured by bolts18 upon supportingledgesl9, forming part of the fixed portion 7 of thecarrier-frame and supported by braces 20. The movable part 8 of thecarrier-frame is provided with 'movable gripping-jaws 21,

- which correspond in location and number with the fixed jaws 17, abovewhich they are placed. These movable jaws are secured bybolts 22 toplates 23, which are carried by arms 24, forming part of the movableportion 8 of the carrier-frame. The arms 24 are connected by arms 25with a yoke 26, which slides in vertical guideways 27 in the fixed part7 of the carrier-frame. The arms 25 also carry the pulleys 28, which arearranged on opposite sides of the machine and also on opposite sides ofa transverse plane centrally intersecting the machine. Their pivotalaxes are indicated at 29, and. the fixed portion 7 of the frame is cutaway, so as to permit them to move vertically with respect thereto.

I have shown each pulley as provided with a guard 30, which forconvenience of manufacture is made in one piece with the correspondingmovable jaw 21. Each pair of grip ping-jaws is provided with afunnel-shaped guide or mouth 31, preferably attached to or formed in onepiece with the movable jaw and serving to maintain the proper relationsbetween the rope (indicated at 32) and thegripping-jaws. These guidesalso serve as stops when the carrier is reversed by pulling the ropethrough it. For this purpose there is formed at each end of the rope 32an enlargement 33, usually in the form of a knot, as indicated in Fig.1, said enlargement being of such size that it will not pass through theguide 31. The rope is pulled through the carrier until the enlargementat one end or the other lodges in the guide of the correspond of thesling-blocks 35.

ing end of the carrier, as indicated in Fig. 1,-

length to reach the ground or barn-floor and enable the operator tograsp the same for the purpose of reversing the carrier by pulling therope 32 through the same in the manner described.

It will be noted that the pulleys 28 are so 7 arranged that thoseportions thereof from which the bight of the rope 32 depends arepractically in alinement transversely of the machine. It follows fromthis that the bight of the rope lies ina transverse plane with respectto the machine and track, the slingblocks 35, supported by this portionof the rope, being so positioned that the bundle is longitudinal,extending with its greatest length in the direction of the track. Thisis a matter of material importance in the handling of the loads, as itobviates the necessity of swinging the bundle around to this positionwhen it has reached the place where it is to be discharged and-also thenecessity of providing special devices for effecting this turning of thebundle.

The trip devices are preferably constructed in substantially the'samemanner as in my prior Letters Patent hereinbefore referred to.

The yoke 26 is provided at its upper end with an extension 36,terminating in a head or enlargement 37. The carriage 3 has mounted init on each side levers 38, pivoted to the carriage at 39 and having arms40, which extend under the head or enlargement 37. The levers 38 alsohave arms 41, carrying rollers 42, which cooperate with the cam-surfacesof the knocker 2, sothat when said rollers come into contact with theknocker the arms 41- are forced outward and the arms 40 upward, engagingthe head or enlargement 37, and thereby lifting the yoke 26 and all ofthe movable part of the carrier-frame, including the movable gripping-jaws. The yoke carries a transverse pin 43, which is adapted to beengaged by a dog 44, pivoted to the fixed part of the carrier-frame at45 and having connected to it the tripping-plate 46, which lies in thepath When the movable frame member is lifted by means of the knocker inthe manner already described, the dog 44 engages by gravity the'pin 43and holds the movable frame member in lifted position, with thegripping-jaws open. When the sling-blocks 35 come into contact with thetripping-plate 46, they lift said plate and disengage the dog 44 fromthe pin 43, permitting the movable frame member to fall. Sincethe'entire weight of the load is supported by the pulleys 28, which arein turn supported by the movable frame member 8, this weight acts toforce the movable grippingjaws 21 BEST AVAILABLE COP the rope 32 tendsto move while the' load is being transported along the track, it will beunderstood that there is no tendency of the gripping-jaws to slip, suchas is present where the supporting-pulleys form an element of the grip'iing aws In order to obviate the necessity of hoisting the load to aheight such as to cause the sling-blocks 35 to automatically drop theropelock, I provide a rope 17, connected to the tripping-plate 46 andpassing over a pulley 4:8

' on the fixed part 7 of the carrier-frame, whence it extends downward,so-as to be conveniently reached by the operator. By means of this arope 47 it is possible to lock the load with respect to the carrier assoon as it has reached any desired height, so that it is not necessaryin the earlier stages of the operation of building up the piles of hayto lift the load to the maximum height in order to automatically operatethe tripping mechanism.

The general operation of the carrier is the same as that of the carrierdescribed in my prior Letters Patent hereinbefore referred to. When thecarrier returns to the loading-place, where the knocker 2 is located,the movable portion of the frame will be lifted through the medium ofthe levers 38 and the gripping-jaws will be opened, so as to permit thebi ght of the rope 32 to be lowered to a position such that thesling-blocks 35 may be connected to the sling which carries the load.

' The header enlargement 37 engages with the knocker in such a way as toprevent the car rier from moving along the track, so that when the rope32 is pulled the load will be hoisted to an elevated position. Thishoisting operation continues until the tripping mechanism is actuatedeither through the rope 4:7 or by reason of the contact of theslingblocks 35 with the contact-plate 46. When the tripping mechanism isthus operated, the dog 14 is disengaged from the pin 43 and the movablemember of the carrier-frame falls. Drawn down by the weight of the loadthe gripping-jaws 21 firmly clamp the rope 32 against the gripping-jaws17, so that the rope cannot move relatively to the carrier. At the sametime the head 37 drops below the knocker, so as to permit the carrier tomove along the track, and the load is drawn along the track by means ofthe rope 32 to the point where it is to be discharged, being conveyedwith its longer axis in the direction of the track, so that it is readyto be discharged in nosition in which it arrives at the place of r Incase it is desired to reverse f travel of the carrier from the may beaccomplished either by drawing the rope 32 through the carrier or byturning the body of the carrier around relatively to the carriage fromwhich it is suspended. In the former case the reversal is effected bypulling the rope through by means of either one of the smaller ropes 34,connected to its ends, until the knot or enlargement 33 at the fartherend of the rope lodges in the guide 31. In the latter case it is onlynecessary to exert a pull in the proper direction upon the rope 32,whereupon the bolt 9 will yield, sliding upon the incline 16, and thecarrier proper will make a half -revolution relatively to the carriage,being automatically stopped by the contact of the bolt- 9 with thestop-shoulder 15 on the opposite side of the turn-table or swivelingconnection between the carrier proper and carriage. If desired, the bolt9 may be released at any time by a downward pull upon the rope 13.

It will be noted that in order that the bight of the rope shall hangtransversely with respect to the carrier the pulleys 28 must belaterally offset with respect to the central longitudinal plane of thecarrier, and since the grippingjaws are arranged in alinement with thepulleys said gripping-jaws are also laterally offset with respect tosaid central longitudinal plane. It therefore follows that when tractionis exerted upon the lead of the hoisting and hauling rope 32 to causethe carrier to travel along the track the pull of said rope is notcentral and there is a tendency for the body of the carrier to turnrelatively to the carriage, the guide 31 tending to move into the planeof the track. This turning tendency is effectually resisted by thelocking mechanism which I have provided between the body of the carrierand the carriage.

It will be noted that the offset stop-shoulders 15 are so located thatthe pull of the rope 32 tends to bring the bolt 9 against the shoulder15 of the particular notch or recess 1 1 with which the bolt is engaged,so that no movement of rotation of the body of the carrier is caused bythe hauling on the rope 32. At the same time it is possible to reversethe body of the carrier by turning it in the opposite direction,although the bolt 9 effectually prevents accidental displacement of thebody of the carrier relatively to the carriage. This feature ofmyinvention is applicable not only to the particular type of carrierhere shown, but also to the other types of carrier set forth in my threeprior Letters Patent hereinbefore referred to and to other carriers ofthe swiveling class. It will be noted that this looking mechanism isentirely independent of the hoisting and tripping mechanism, so that thecarrier may be turned to reverse the direction of travel irrespective ofwhether the load is hoisted or not and irrespective of the position ofthe tripping mechanism.

I do not wish to be understood as limiting myself to the precise detailsof construction BEST AVAILABLE coi hereinbefore described, and shown inthe accompanying drawings, as it is obvious that these details maybemodified Without departing from the principle of my invention.
